I've owned just about every gun mentioned here but the Rorbaugh. In my experience the P11 is too big for pocket carry in anything tighter than cargo pants, and while it's more contoured than the Glock 26 (and I've got both of these guns in front of me right now) they're really about the same size, but the KT is 5 ounces lighter when loaded than the Glock.
The P3AT (sold mine but still have a P32) is, in my experience a hard gun for some to shoot, and while it's not as reliable as the P32's I've shot it does work well once broken in and fluffed and buffed. The P32 is a real pussycat to shoot.
The polymer Kahr's are nice and flat, light and well made, but the one I owned was unreliable, even after a trip back to the factory. The metal framed Kahr's I've seen have been excellent, but the polymer models seem to have some teething problems. And no, I wasn't limp wristing the gun, I can shoot my KT P40 with no problems. For the price Kahr wants I want it reliable out of the box.
The new KT PF9 is certainly interesting, but it's going to be 3 months before it becomes available and based on KT's track record it will be at least 6 months before they get them working right. I hope they prove me wrong, but so far it's the way they've been.
Your best bet, IMHO, is a KT P32 or P3AT as a BUG with a Glock 26 IWB and for spare mags carry the 17 round mags. Put a Concealable Control baseplate on the 10 round mag. Get a good IWB holster and a good gun belt. For the BUG get the Desantis Sting pocket holster and a spare mag.
